  • 3 TBSP ground flax seed
  • 2 sweet potatoes (or 1 large)
  • 2 cans garbanzo beans or white beans, drained (or 3 cups, cooked)
  • 1 TBSP each of cumin, smoked paprika, garlic powder, onion powder
  • 1/2 tsp chipotle chili powder or chipotle hot sauce
  • 1 tsp salt
  • 1/2 tsp pepper
  • 1/2 cup rolled oats
  • 2 TBSP nutritional yeast (optional)
  • 3 TBSP ketchup or tomato paste
  • 1/2 cup sunflower seeds
  • 1/2 cup chopped cilantro

For Serving with the Burgers

  • 8 whole wheat hamburger buns
  • BBQ Sauce, Ketchup, Mustard, Ranch dressing, etc.
  • lettuce, tomato, sprouts, cucumber, pickled veggies
  • Maple Mustard sauce is delicious: mix equal parts Dijon mustard (or your favorite mustard) with maple syrup


  1. Bake the sweet potato in the microwave for about 8-10 minutes, until soft, or in a crock pot or oven for 1-2 hours.

  2. Mix the ground flax seed with 1/3 cup water in a large bowl. Let sit for 5 minutes. This creates a flax "egg" that helps the burgers bind together and not be crumbly.

  3. Cut the sweet potato open and scoop the baked potato into a measuring cup. Measure 2 cups of potato in the large bowl with the flax seed. Mash with a fork.

  4. Add the beans, and mash until most of the beans are no longer in tact, but they create some texture. You don't want it smooth puree or your burger will be more mushy.

  5. Add all remaining ingredients and stir well. Taste, and add more spices or hot sauce to make it spicier, if desired. It should be delicious!

  6. Form patties by filling a 1/2 cup measure and whacking the burger mixture out of the measuring cup into your hand, then pressing into a burger patty. Makes 8-9 burgers.

  7. Place them on parchment paper or a silicone baking mat on a cookie sheet. Bake at 400 degrees for 15 minutes, flip over, then bake about 10 more, until firm and golden.

    You can also put them in the air fryer for about 10 minutes, flipping, then 5 minutes more.

  8. Serve on buns with lettuce, tomato, your favorite condiments. Sweet and spicy sauces go really well with this burger, like BBQ sauce, hot sauce, or maple mustard sauce made by stirring together equal parts mustard and maple syrup.

  9. To freeze

  10. To freeze, you can freeze the unbaked patties in a container with wax paper between the patties to separate them. Then, bake them or put them directly in the air fryer until golden and firm (a few minutes longer than directed above).

    You can also freeze the baked patties and microwave them for a quick meal.
